Fluoropolymer—amino terminated polydiorganosiloxane compositions for textile treatments

Abstract

Treatment of textiles by a fluoropolymer-amino terminated polydiorganosiloxane composition is disclosed. The fluoropolymer-amino terminated polydiorganosiloxane compositions are prepared by combining a fluoropolymer and an amino terminated polydiorganosiloxane. The resulting compositions improve the hand or feel of the fabric without significantly diminishing oil repellency properties associated with fluoropolymers.

1. A fabric treatment composition comprising;
 A) a fluoropolymer, 
 B) an amino terminated polydiorganosiloxane, 
 
       wherein the amino terminated polydiorganosiloxane has the formula
   A-(R 2 SiO) C -A, 
 
       where A is an amino-functional hydrocarbon group, R is an alkyl or aryl group, and c is greater than zero. 
     
     
       2. The composition according to  claim 1  where R is methyl. 
     
     
       3. The composition according to  claim 1  where c is 1–200. 
     
     
       4. The composition according to  claim 1  where A is CH 2 CH 2 CH 2 NH 2  or CH 2 CH(CH 3 )CH 2 NH(CH 3 ). 
     
     
       5. A method of treating fibers or textiles comprising;
 I) mixing,
 A) a fluoropolymer, 
 B) an amino terminated polydiorganosiloxane, and 
 
 II) applying the mixture of step I on fibers or textiles, 
 
       wherein the amino terminated polydiorganosiloxane has the formula
   A-(R 2 SiO) c -A, 
 
       where A is an amino-functional hydrocarbon group. R is an alkyl or aryl group, and c is greater than zero. 
     
     
       6. A fiber or textile prepared by the treatment method of  claim 5 .
